-' Application filed October 15, 1924. Serial No. "743334;.

T 0 all whom it may concern.

Be it known that I, Anciiin EDGAR Low, 21 subject of the King of GreatBritain, and resident of the city of Ottawa, in the Province of Ontarioand Dominion of Canada, have invented certain new and usefulImprovements in Grommet Locks, of which the following is aspecification. v

This invention relates to improvements in looks, and more particularlyto, improvements in gromn'iet locks, and the objects of the inventionare to provide a simply constructed and effective lock of this characterto secure the locking of a bag closed by means of tie cords or ropespassing through grommets, the locking device being attached to the bagitself over one of the grommets.

Further objects are the provision of a lock of this character adapted tosecurely lock tie ropes or the like used as securing 'means for anyother purpose than tying a bag.

till further objects are to provide an efficient lock of this characterthat will not in any way injure or cut the tie cords or ropes with whichit engages, and in which the several parts will more satisfactorilyperform the various functions required of them, also to provide a lockof this character that can be manufactured and placed on the market at acomparatively low price.

With these and other objects in view the improved lock consistsessentially of a grooved cramping bolt and lever adapted to engage thetie-r0pe of a, bag to secure the same in any desired place, the lockingmeans being automatically held in looking position.

Referring now to the drawings, in which like characters of referenceindicate corresponding parts in each figure:

Figure 1 is a front elevation of an embodiment of the improved lockmounted on a suitable back plate.

Figure 2 is a similar view with the lock casing removed and showing thelock in open position.

Figure. 3 is a similar view to Figure 2, showing the lock closed or inlocked position.

Figure 1 is a section through the lock.

Figure 5 is a perspective detail of the grooved cramping bolt and lever.

Figure 6 is a similar view of the key. Figure 7 is a plan view of adiameter plate adapted to be used on the inside of a bag and to whichthe lock-retaining or back plate is riveted through the bag.

Figure 8 is a perspective detail of a modified form of cramping bolt andlever showing the grooves 18 extended to form holes 18 and 19 one abovethe other.

In the drawings, in which an embodiment of my device is illustrated, 10indicates the lock casing, with grommet aperture 11 and key aperture 12,and here shown as attached to aqalate 1 1- by means of a retaining screw13, it being understood that the casing may be secured in any otherwell-known manner, all as illustrated in Figure 1.

Referring now more particularly to the mechanism as illustrated inFigures 2, 3 and 4-, this consists of a vertically arranged bolt 15rotatably supported in bracket members 16 and 17 screw-secured to theback plate 14. This bolt 15 is grooved on opposite sides at the top at18 and 19, thus constituting a grooved cramping bolt, and is designed toregister with the grommet opening in the back plate and with a similaropening 20 in the supporting bracket 16, both in turn registering withthe grommet opening 11 in the casing whereby, as

shown'in Figure 1, the tie-ropes or cords of the bag will extend throughthe grooves in the bolt and through the opening in the bolt-supportingbracket, and then through the opening in the look casing, the bolt 15being adapted in one position to receive tieropes or the liketherethrough, and in locked position expanding, as it were, the fulldiameter of bolt crosswise of the opening, to hold the tie-ropessecurely. Formed integral with the other end of the bolt is anoperatinglever 21 provided with a suitable handle 22. Substantially midway of itslength the bolt 15 is recessed at 9 to engage with a locking bolt 23operatively supported in a bracket 24 screw-secured at 25 to the backplate, the bolt being automatically held in locking position by a spring26 engaging at one end wit-h the bolt 23, and the loose end of which iscoiled on a suitable pin 27 carried by the back plate. This bolt 23 isreciprocally mounted on the back plate at 28 and is formed with an arm29 adapted to engage with the wards 30 of a key 21. 32 is a stop memberon the bolt 15 adapted to engage with stop means 33 on the lowersupporting bracket 16 to limit the travel, in open position, of the bolt15.,
